Yield impact of source-sink-regulated senescence in hybrid maize and genetic architecture in exPVP inbreds.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik - 27 Apr 2026

Abstract excerpt

Prior genetic studies on source-sink-regulated senescence in maize have characterized some genes associated with the trait, but the impact on yield is unknown and the molecular understanding of this trait is still in its infancy. We phenotyped source-sink-regulated senescence in a commercial maize exPVP inbred population and assessed its correlation with yield and other commercially relevant agronomic traits in...
